And I have to add a historical point here, because when we visited Mt. St. Helens I couldn't help but wondering who was "St. Helens." I've heard of St. Helen, but not a "Helens." So...I looked it up. The peak was named in 1792 after Alleyne Fitzherbert, who was British Ambassador to Spain at the time and held the title "Baron St. Helens." (The explorer who named Mt. St. Helens was Captain George Vancouver. Although he chose fellow countryman Baron St. Helens as the namesake for this volcano, Vancouver chose to honor fellow British naval officers for other nearby mountains: Hood, Rainier, and Baker.)
As we drove closer to the peak, it was really interesting to drive through the reforested areas because all of the trees were the same species, and all of the trees were exactly the same age. I never realized it before, but it's normal to observe lots of variety on mountain landscapes, with trees of different varieties and ages. It was weird to not see that usual variation on the mountainside. When we were driving through this area, it felt like we were in some virtual world with CGI effects - it was like we saw the same tree over and over and over...
Near the crater, we visited Johnston Ridge Observatory (which is the best place to go to observe the geological changes which have occurred since the eruption in 1980). A lot of the land around the volcano peak has been preserved since the eruption. Scientists don't want the land reforested or manipulated, because they want to observe the natural ecological/geological processes. For that reason, there is still a lot of the volcanic eruption. This image shows a ridge which is right next to the volcanic peak. If you click on the image, you'll see that the whole mountain is covered with trees that have been pushed over in the same direction (i.e. away from the volcanic blast). It was really strange to see many slopes covered with dead tree trunks that were all lying in the same direction.
If you want to see some really cool photos of Mt. St. Helens before and after the 1980 eruption, go here. It's crazy to compare the two photographs at the beginning of the slideshow - the mountain looked so different beforehand.

Wow, thanks for posting all those cool pictures of your adventure and the links to more info.
I've had a very uneducated "obsession" with Mt. St. Helens since I was a kid. When I was growing up, my mom had a little container of ash that she bought from the eruption. It sat in our bathroom cupboard (of all places) during my childhood. So, I have always wanted to go there. It was really cool to read about your visit and learn about the history.
The picture of those trees is crazy! It looks computer generated like you said, but it's also really vibrant with the colors being so in sync.
I looked through your other pictures on picasa and they are very cool! Looks like you guys had a great trip!
